y PLANE.

To all whom t may concern:

Be it known that I, LOUIS HANEBERG, a citizen of the United States, residing at Bullrun, in the countyr of Clackamas and State of Oregon, have invented new and useful Improvements in Planes, of which the following is a specification.

This invention relates to improvements in planes for use by carpenters and other workers in wood and especially with reference to the provision of a tool of this character which may be adjusted or modified in size and thereby adapted for use either as a smoothing plane, a jack-plane or a jointerplane, as may be desired.

The invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings Figure 1 is a vertical longitudinal sectional view of a plane constructed in accordance with my invention, and showing the same arranged for use as a jointer-plane.

Fig. 2 is an elevation of the same, with the parts disconnected from one another.

Fig. 3 is a plan of the same.

Fig. 4 is a vertical transverse sectional view of the same. l My improved plane comprises a central member or body 1, which is made of iron or steel and comprises a shoe or bottom 2 and side walls or anges 3. Said walls or flanges are provided in their ends with V- shaped dovetail notches 4, 5 which are reversely arranged as shown, and are respectively at the front and rear ends of the member 1. The frog 6 on which the usual bit is placed is also made of metal and 1s integral with a plate which bears on the bottom `2 and is formed with side flanges or walls 8 which are secured to the inner sides of the side walls 3 and are co-extensive therewith so that the said flanges or walls 8 form bottoms for the dovetail notches. The central portion of the plate 7 is formed with longitudinally arranged osets 9, 10 which form slots 11, 12 which extend respectively to the front and rear ends of the .member 1. The usual knob 13 is secured on the offset 9 by a screw 14, the lower end of which is conical in form. The usual handle 15 is secured on the offset 10 by a screw 16 and also by a set-screw 17 the lower end of the set-screw being conical.

The body 1 when equipped with a suitable bit forms a smoothing plane.

Application led May 4, 1918.

i Specification of Letters Patent. Patented Jan, 21, 1919 Serial No. 232,617.

An extension 18 is provided for the front end of the plane and to forma jack-plane when said extension is attached to the front end of the body 1. The said extension is made of iron or steel and comprises a bottom or vshoe 19 and side walls or flanges 20, the rear ends of which are V-shaped as at 21, to form dovetail tongues which are adapted to closely lit in the dovetail notches 4. In the bottoni of the extension 18 is a connecting plate 22 which is secured thereto and the rear ortion of which extends rearwardly there rom and is adapted to enter the slot 11 and is provided with an inverted conical opening 23 for engagement by the lower end of the screw 14 so that the screw serves to firmly draw and clamp the extension 18 against the rear end of the body or member 1 as well as to secure the knob 13 in place.

When the extension 18 is thus secured to the rear end of the member 1 the plane is arranged for use as a jack-plane, as will be understood.

I also provide a rear extension 24 which is similar in construction to the construction 18 and the side walls of which are provided at their front ends with V-shaped tongues 25 to enter the notches 5. The connecting plate 26 of the extension 24 projects at its front portion from the front end of said extension and is adapted to enter the slot 12 and has a conical opening 27 with which the conical lower end of the setscrew 17 engages so that said setscrew serves to closely draw and clamp said extension 24 to the rear end of the member 1.

When the extension 24 is thus secured the plane forms a jointer-plane.

Owing to the provision of the side walls 8 of the frog member 6 and which cover the inner sides of the dovetail notches the dovetail projections or tongues of the front and rear extensions bear directly against said walls or flanges 8 and lateral displacement of the extensions 18 and 24 is absolutely While I have herein shown and described a preferred form of my invention, I would have it understood that changes may be made in the form, proportion and construction of the several parts, without departing from lthe spirit of my invention and Within the scope of the appended claims.

Having thus described my invention, I claim 1. In a plane, a main member having *a longitudinally arranged slot, an extension memberl having "a 'connecting plat-e projectn ing therefrom and arranged to :enter the slot, a handle on the main member and a screw securing thefhandle to the mainlmember and also securing theplateinthe slot.

2. In a plane, a main member yhaving a longitudinally arranged slot, :anfextension member having a connecting `plate-projecting therefrom and a'rmnged to yenter the slot, a handle on the main memberandga screw securngthe handle to the main member and also securing lthe .plate in lthe fslot, said plate having -a conical opening and the screw having a conical point to engage in said opening.

53. 'In aplane, amain member ha ving side Walls provided with notches at the ends, said main member being also provided With a "frog member having side Walls which form the inner-sides or bottoms of .SaidhOt-cheS,

extension members for the plane having side walls provided With projections to enter said notches and means to detachablyfseeure eai-d extension members. 'i

4. In plane, a main 'membelg a Vfrog memberin the mainmember and `pnovded -witlrabottom 1portion having an ofSet forming llongitudinal slot, and an .extension member having-ay Iplate .proj eating .therefrom vvandarranged to engage infsaid slot.
